January 4, 2017 - Rare Snow Falls at the Edge of Sahara Desert
In mid-December 2016, a rarity occurred on the edge of the Sahara Desert in northwest Africa. It snowed. Landsat 7’s Enhanced Thematic Mapper Plus (ETM+) sensor captured the image that shows the white covering on the caramel-colored landscape southwest of the Algerian community of Ain Sefra. All the snow except that at the highest elevations melted soon after, a fact Landsat 8 confirmed when it passed overhead on December 27. Ain Sefra’s last snowfall occurred on February 18, 1979.
